본 고안은 대형트럭의 흡기시스템(Intake System)에 있어서, 차량의 캡(Cap)후부에 위치된 에어 흡기관의 구조에 관한 것으로 보다 상세하게로는, 에어흡기관의 덕트(Duct)본체부내에 에어안내판이 설치된 에어챔버를 마련하여 유입되는 에어를 체적변화로 인해 소음 및 진동발생을 감소시키며, 특히 덕트 본체부내의 에어 부압 발생을 현저하게 감소시키고, 유속변화에 따른 에어의 흡입속도를 증가시킬수 있도록 한 대형트럭의 에어흡기간 구조에 관한 것이다.The present invention relates to a structure of an air intake pipe located in a rear side of a cap of a vehicle in an intake system of a large truck, and more specifically, in a duct body part of an air intake pipe. By installing an air chamber with an air guide plate, the inflow of air reduces noise and vibrations due to volume changes, and in particular, significantly reduces the occurrence of negative air pressure in the duct body, and increases the suction speed of the air according to the flow rate change. The air suction structure of a large truck.

It is made of a structure that allows the suction into the engine.

상기와 같은 종래의 에어흡기관은, 차량의 주행중 신선한 외부공기가 에어흡기관의 덕트카버를 통해 엔진으로 유입되어지며, 차량의 주행시 발생되는 에어의 와류현상에 의해 외부공간의 흡입이 원할하게 이루어지지 않게되며, 이로인한 덕트내부의 에어부압이 상승하게 되는 단점이 있는 것이다.In the conventional air intake pipe as described above, fresh outside air is introduced into the engine through the duct cover of the air intake pipe while the vehicle is running, and the intake of the external space is made smooth by the vortex phenomenon of air generated when the vehicle is driven. There is a disadvantage in that it is not supported, thereby increasing the air negative pressure in the duct.

또한, 에어흡기관을 통해 흡입되는 공기의 흐름에 의해 소음과 진동이 발생하고, 엔진으로부터 발생되는 더운공기가 유입되어 엔진의 냉각성능을 저하시키게 되는 등 많은 문제점이 있었던 것이다.In addition, noise and vibration are generated by the flow of air sucked through the air intake pipe, and hot air generated from the engine is introduced to reduce the cooling performance of the engine.

상기 목적을 달성하기 위한 기술적인 구성으로서 본 고안은, 차량의 캡 후방에 설치되는 에어흡기관의 덕트 본체부 상측에 레인캡(Rain Cap)이 착설되며, 상기 덕트본체부의 하측내부에는 흡입공기의 흐름을 안내하는 안내판이 설치된 에어챔버로 구성되는 에어 흡기관을 마련함에 의한다.As a technical configuration for achieving the above object, the present invention, a rain cap is installed on the upper side of the duct body portion of the air intake pipe that is installed behind the cab of the vehicle, the lower inside of the duct body portion of the intake air By providing an air intake pipe consisting of an air chamber is installed guide plate for guiding the flow.

이하, 첨부된 도면에 의거하여 본 고안의 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 따른 에어흡기관의 사시도이고, 제2도는 본 고안 에어흡기관의 배면 구조도로서, 차량의 캡(1)후방에 설치되는 에어흡기관(2)의 덕트 본체부(3)상측으로 레인캡(4)이 착설되며, 상기 덕트 본체부(3)의 하측에는 내부에 흡입공기의 흐름을 안내하는 안내판(5)(5')이 설치된 에어챔버(6)가 형성되는 구조로 이루어진다.1 is a perspective view of an air intake pipe according to the present invention, and FIG. 2 is a rear structural view of the air intake pipe according to the present invention, and the duct body part 3 of the air intake pipe 2 installed behind the cap 1 of the vehicle. Rain cap (4) is installed on the upper side, the lower side of the duct body portion (3) has a structure in which an air chamber (6) provided with a guide plate (5) (5 ') for guiding the flow of intake air therein is formed.
